          MDEV-22748 MariaDB crash on WITH RECURSIVE large query

      was merged into 10.5, galera.wsrep_strict_ddl started to fail, it times out because the test hangs on the line

      CREATE VIEW x1 AS SELECT * FROM before_t1;

      The first server gets stuck in this loop:

      bool st_select_lex::cleanup()
      		 
      {
      		 
        ...
      		 
        for (TABLE_LIST *tbl= get_table_list(); tbl; tbl= tbl->next_local)
      		 
        {

      and tbl == tbl->next_local, so it loops there forever.

      Nothing fails in 10.4, so presumably the fix was incorrectly merged into 10.5
